This operator is meant to provide a more Kubernetes-native installation method for AWX via an AWX Custom Resource Definition (CRD).
This Kubernetes Operator is meant to be deployed in your Kubernetes cluster(s) and can manage one or more AWX instances in any namespace.
If you do not have an existing cluster, the awx-operator
can be deployed on a Minikube cluster for testing purposes. Due to different OS and hardware environments, please refer to the official Minikube documentation for further information.

It is not required for kubectl
to be separately installed since it comes already wrapped inside minikube. As demonstrated above, simply prefix minikube kubectl --
before kubectl command, i.e. kubectl get nodes
would become minikube kubectl -- get nodes
Let's create an alias for easier usage:
$ alias kubectl="minikube kubectl --"
Once you have a running Kubernetes cluster, you can deploy AWX Operator into your cluster using Kustomize. Follow the instructions here to install the latest version of Kustomize: https://kubectl.docs.kubernetes.io/installation/kustomize/
First, create a file called kustomization.yaml
with the following content:
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
# Find the latest tag here: https://github.com/ansible/awx-operator/releases
- github.com/ansible/awx-operator/config/default?ref=<tag>
# Set the image tags to match the git version from above
images:
- name: quay.io/ansible/awx-operator
newTag: <tag>
# Specify a custom namespace in which to install AWX
namespace: awx
TIP: If you need to change any of the default settings for the operator (such as resources.limits), you can add patches at the bottom of your kustomization.yaml file.
Install the manifests by running this:
$ kustomize build . | kubectl apply -f -
namespace/awx created
customresourcedefinition.apiextensions.k8s.io/awxbackups.awx.ansible.com created
customresourcedefinition.apiextensions.k8s.io/awxrestores.awx.ansible.com created
customresourcedefinition.apiextensions.k8s.io/awxs.awx.ansible.com created
serviceaccount/awx-operator-controller-manager created
role.rbac.authorization.k8s.io/awx-operator-awx-manager-role created
role.rbac.authorization.k8s.io/awx-operator-leader-election-role created
clusterrole.rbac.authorization.k8s.io/awx-operator-metrics-reader created
clusterrole.rbac.authorization.k8s.io/awx-operator-proxy-role created

configmap/awx-operator-awx-manager-config created
service/awx-operator-controller-manager-metrics-service created
deployment.apps/awx-operator-controller-manager created
Wait a bit and you should have the awx-operator
running:
$ kubectl get pods -n awx
NAME READY STATUS RESTARTS AGE
awx-operator-controller-manager-66ccd8f997-rhd4z 2/2 Running 0 11s
So we don't have to keep repeating -n awx
, let's set the current namespace for kubectl
:
$ kubectl config set-context --current --namespace=awx
Next, create a file named awx-demo.yaml
in the same folder with the suggested content below. The metadata.name
you provide will be the name of the resulting AWX deployment.
Note: If you deploy more than one AWX instance to the same namespace, be sure to use unique names.
---
apiVersion: awx.ansible.com/v1beta1
kind: AWX
metadata:
name: awx-demo
spec:
service_type: nodeport
Make sure to add this new file to the list of "resources" in your kustomization.yaml
file:
...
resources:
- github.com/ansible/awx-operator/config/default?ref=<tag>
# Add this extra line:
- awx-demo.yaml
...
Finally, run kustomize
again to create the AWX instance in your cluster:
kustomize build . | kubectl apply -f -
After a few minutes, the new AWX instance will be deployed. You can look at the operator pod logs in order to know where the installation process is at:
$ kubectl logs -f deployments/awx-operator-controller-manager -c awx-manager
After a few seconds, you should see the operator begin to create new resources:
$ kubectl get pods -l "app.kubernetes.io/managed-by=awx-operator"
NAME READY STATUS RESTARTS AGE
awx-demo-77d96f88d5-pnhr8 4/4 Running 0 3m24s
awx-demo-postgres-0 1/1 Running 0 3m34s
$ kubectl get svc -l "app.kubernetes.io/managed-by=awx-operator"
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
awx-demo-postgres ClusterIP None <none> 5432/TCP 4m4s
awx-demo-service NodePort 10.109.40.38 <none> 80:31006/TCP 3m56s
Once deployed, the AWX instance will be accessible by running:
$ minikube service awx-demo-service --url -n $NAMESPACE
By default, the admin user is admin
and the password is available in the <resourcename>-admin-password
secret. To retrieve the admin password, run:
$ kubectl get secret awx-demo-admin-password -o jsonpath="{.data.password}" | base64 --decode

NAME CHART VERSION APP VERSION DESCRIPTION
awx-operator/awx-operator 0.17.1 0.17.1 A Helm chart for the AWX Operator
$ helm install my-awx-operator awx-operator/awx-operator
NAME: my-awx-operator
LAST DEPLOYED: Thu Feb 17 22:09:05 2022
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Helm Chart 0.17.1
There are three variables that are customizable for the admin user account creation.
Name | Description | Default |
---|---|---|
admin_user | Name of the admin user | admin |
admin_email | Email of the admin user | [email protected] |
admin_password_secret | Secret that contains the admin user password | Empty string |
โ ๏ธ admin_password_secret must be a Kubernetes secret and not your text clear password.
If admin_password_secret
is not provided, the operator will look for a secret named <resourcename>-admin-password
for the admin password. If it is not present, the operator will generate a password and create a Secret from it named <resourcename>-admin-password
.
To retrieve the admin password, run kubectl get secret <resourcename>-admin-password -o jsonpath="{.data.password}" | base64 --decode
The secret that is expected to be passed should be formatted as follow:
---
apiVersion: v1
kind: Secret
metadata:
name: <resourcename>-admin-password
namespace: <target namespace>
stringData:
password: mysuperlongpassword
If the service_type
is not specified, the ClusterIP
service will be used for your AWX Tower service.
The service_type
supported options are: ClusterIP
, LoadBalancer
and NodePort
.
The following variables are customizable for any service_type
Name | Description | Default |
---|---|---|
service_labels | Add custom labels | Empty string |
service_annotations | Add service annotations | Empty string |
---
spec:
...
service_type: ClusterIP
service_annotations: |
environment: testing
service_labels: |
environment: testing
- LoadBalancer
The following variables are customizable only when service_type=LoadBalancer
Name | Description | Default |
---|---|---|
loadbalancer_protocol | Protocol to use for Loadbalancer ingress | http |
loadbalancer_port | Port used for Loadbalancer ingress | 80 |
---
spec:
...
service_type: LoadBalancer
loadbalancer_protocol: https
loadbalancer_port: 443
service_annotations: |
environment: testing
service_labels: |
environment: testing
When setting up a Load Balancer for HTTPS you will be required to set the loadbalancer_port
to move the port away from 80
.
The HTTPS Load Balancer also uses SSL termination at the Load Balancer level and will offload traffic to AWX over HTTP.
- NodePort
The following variables are customizable only when service_type=NodePort
Name | Description | Default |
---|---|---|
nodeport_port | Port used for NodePort | 30080 |
---
spec:
...
service_type: NodePort
nodeport_port: 30080
By default, the AWX operator is not opinionated and won't force a specific ingress type on you. So, when the ingress_type
is not specified, it will default to none
and nothing ingress-wise will be created.
The ingress_type
supported options are: none
, ingress
and route
. To toggle between these options, you can add the following to your AWX CRD:
- None
---
spec:
...
ingress_type: none
- Generic Ingress Controller
The following variables are customizable when ingress_type=ingress
. The ingress
type creates an Ingress resource as documented which can be shared with many other Ingress Controllers as listed.
Name | Description | Default |
---|---|---|
ingress_annotations | Ingress annotations | Empty string |
ingress_tls_secret | Secret that contains the TLS information | Empty string |
hostname | Define the FQDN | {{ meta.name }}.example.com |
ingress_path | Define the ingress path to the service | / |
ingress_path_type | Define the type of the path (for LBs) | Prefix |
---
spec:
...
ingress_type: ingress
hostname: awx-demo.example.com
ingress_annotations: |
environment: testing
- Route
The following variables are customizable when ingress_type=route
Name | Description | Default |
---|---|---|
route_host | Common name the route answers for | <instance-name>-<namespace>-<routerCanonicalHostname> |
route_tls_termination_mechanism | TLS Termination mechanism (Edge, Passthrough) | Edge |
route_tls_secret | Secret that contains the TLS information | Empty string |
---
spec:
...
ingress_type: route
route_host: awx-demo.example.com
route_tls_termination_mechanism: Passthrough
route_tls_secret: custom-route-tls-secret-name
To configure AWX to use an external database, the Custom Resource needs to know about the connection details. To do this, create a k8s secret with those connection details and specify the name of the secret as postgres_configuration_secret
at the CR spec level.
The secret should be formatted as follows:
---
apiVersion: v1
kind: Secret
metadata:
name: <resourcename>-postgres-configuration
namespace: <target namespace>
stringData:
host: <external ip or url resolvable by the cluster>
port: <external port, this usually defaults to 5432>
database: <desired database name>
username: <username to connect as>
password: <password to connect with>
sslmode: prefer
type: unmanaged
type: Opaque
Please ensure that the value for the variable
password
should not contain single or double quotes ('
,"
) or backslashes (\
) to avoid any issues during deployment, backup or restoration.
It is possible to set a specific username, password, port, or database, but still have the database managed by the operator. In this case, when creating the postgres-configuration secret, the
type: managed
field should be added.
Note: The variable sslmode
is valid for external
databases only. The allowed values are: prefer
, disable
, allow
, require
, verify-ca
, verify-full
.
Once the secret is created, you can specify it on your spec:
---
spec:
...
postgres_configuration_secret: <name-of-your-secret>
For instructions on how to migrate from an older version of AWX, see migration.md.
If you don't have access to an external PostgreSQL service, the AWX operator can deploy one for you along side the AWX instance itself.
The following variables are customizable for the managed PostgreSQL service
Name | Description | Default |
---|---|---|
postgres_image | Path of the image to pull | postgres:12 |
postgres_init_container_resource_requirements | Database init container resource requirements | requests: {cpu: 10m, memory: 64Mi} |
postgres_resource_requirements | PostgreSQL container resource requirements | requests: {cpu: 10m, memory: 64Mi} |
postgres_storage_requirements | PostgreSQL container storage requirements | requests: {storage: 8Gi} |
postgres_storage_class | PostgreSQL PV storage class | Empty string |
postgres_data_path | PostgreSQL data path | /var/lib/postgresql/data/pgdata |
postgres_priority_class | Priority class used for PostgreSQL pod | Empty string |
Example of customization could be:
---
spec:
...
postgres_resource_requirements:
requests:
cpu: 500m
memory: 2Gi
limits:
cpu: 1
memory: 4Gi
postgres_storage_requirements:
requests:
storage: 8Gi
limits:
storage: 50Gi
postgres_storage_class: fast-ssd
postgres_extra_args:
- '-c'
- 'max_connections=1000'
Note: If postgres_storage_class
is not defined, Postgres will store it's data on a volume using the default storage class for your cluster.
There are a few variables that are customizable for awx the image management.
Name | Description | Default |
---|---|---|
image | Path of the image to pull | quay.io/ansible/awx |
image_version | Image version to pull | value of DEFAULT_AWX_VERSION or latest |
image_pull_policy | The pull policy to adopt | IfNotPresent |
image_pull_secrets | The pull secrets to use | None |
ee_images | A list of EEs to register | quay.io/ansible/awx-ee:latest |
redis_image | Path of the image to pull | docker.io/redis |
redis_image_version | Image version to pull | latest |
Example of customization could be:
---
spec:
...
image: myorg/my-custom-awx
image_version: latest
image_pull_policy: Always
image_pull_secrets:
- pull_secret_name
ee_images:
- name: my-custom-awx-ee
image: myorg/my-custom-awx-ee
Note: The image
and image_version
are intended for local mirroring scenarios. Please note that using a version of AWX other than the one bundled with the awx-operator
is not supported. For the default values, check the main.yml file.
Depending on your kubernetes cluster and settings you might need to grant some capabilities to the redis container so it can start. Set the redis_capabilities
option so the capabilities are added in the deployment.
---
spec:
...
redis_capabilities:
- CHOWN
- SETUID
- SETGID
Depending on the type of tasks that you'll be running, you may find that you need the task pod to run as privileged
. This can open yourself up to a variety of security concerns, so you should be aware (and verify that you have the privileges) to do this if necessary. In order to toggle this feature, you can add the following to your custom resource:
---
spec:
...
task_privileged: true
If you are attempting to do this on an OpenShift cluster, you will need to grant the awx
ServiceAccount the privileged
SCC, which can be done with:
$ oc adm policy add-scc-to-user privileged -z awx
Again, this is the most relaxed SCC that is provided by OpenShift, so be sure to familiarize yourself with the security concerns that accompany this action.
The resource requirements for both, the task and the web containers are configurable - both the lower end (requests) and the upper end (limits).
Name | Description | Default |
---|---|---|
web_resource_requirements | Web container resource requirements | requests: {cpu: 100m, memory: 128Mi} |
task_resource_requirements | Task container resource requirements | requests: {cpu: 100m, memory: 128Mi} |
ee_resource_requirements | EE control plane container resource requirements | requests: {cpu: 100m, memory: 128Mi} |
Example of customization could be:
---
spec:
...
web_resource_requirements:
requests:
cpu: 250m
memory: 2Gi
limits:
cpu: 1000m
memory: 4Gi
task_resource_requirements:
requests:
cpu: 250m
memory: 1Gi
limits:
cpu: 2000m
memory: 2Gi
ee_resource_requirements:
requests:
cpu: 250m
memory: 100Mi
limits:
cpu: 500m
memory: 2Gi
The AWX and Postgres pods can be assigned a custom PriorityClass to rank their importance compared to other pods in your cluster, which determines which pods get evicted first if resources are running low. First, create your PriorityClass if needed. Then set the name of your priority class to the control plane and postgres pods as shown below.
---
apiVersion: awx.ansible.com/v1beta1
kind: AWX
metadata:
name: awx-demo
spec:
...
control_plane_priority_class: awx-demo-high-priority
postgres_priority_class: awx-demo-medium-priority
You can constrain the AWX pods created by the operator to run on a certain subset of nodes. node_selector
and postgres_selector
constrains
the AWX pods to run only on the nodes that match all the specified key/value pairs. tolerations
and postgres_tolerations
allow the AWX
pods to be scheduled onto nodes with matching taints.
The ability to specify topologySpreadConstraints is also allowed through topology_spread_constraints
Name | Description | Default |
---|---|---|
postgres_image | Path of the image to pull | 12 |
postgres_image_version | Image version to pull | 12 |
node_selector | AWX pods' nodeSelector | '' |
topology_spread_constraints | AWX pods' topologySpreadConstraints | '' |
tolerations | AWX pods' tolerations | '' |
annotations | AWX pods' annotations | '' |
postgres_selector | Postgres pods' nodeSelector | '' |
postgres_tolerations | Postgres pods' tolerations | '' |
Example of customization could be:
---
spec:
...
node_selector: |
disktype: ssd
kubernetes.io/arch: amd64
kubernetes.io/os: linux
topology_spread_constraints: |
- maxSkew: 100
topologyKey: "topology.kubernetes.io/zone"
whenUnsatisfiable: "ScheduleAnyway"
labelSelector:
matchLabels:
app.kubernetes.io/name: "<resourcename>"
tolerations: |
- key: "dedicated"
operator: "Equal"
value: "AWX"
effect: "NoSchedule"
postgres_selector: |
disktype: ssd
kubernetes.io/arch: amd64
kubernetes.io/os: linux
postgres_tolerations: |
- key: "dedicated"
operator: "Equal"
value: "AWX"
effect: "NoSchedule"
In cases which you need to trust a custom Certificate Authority, there are few variables you can customize for the awx-operator
.
Trusting a custom Certificate Authority allows the AWX to access network services configured with SSL certificates issued locally, such as cloning a project from from an internal Git server via HTTPS. It is common for these scenarios, experiencing the error unable to verify the first certificate.
Name | Description | Default |
---|---|---|
ldap_cacert_secret | LDAP Certificate Authority secret name | '' |
ldap_password_secret | LDAP BIND DN Password secret name | '' |
bundle_cacert_secret | Certificate Authority secret name | '' |
Please note the awx-operator will look for the data field ldap-ca.crt in the specified secret when using the ldap_cacert_secret , whereas the data field bundle-ca.crt is required for bundle_cacert_secret parameter. |
Example of customization could be:
---
spec:
...
ldap_cacert_secret: <resourcename>-custom-certs
ldap_password_secret: <resourcename>-ldap-password
bundle_cacert_secret: <resourcename>-custom-certs
To create the secrets, you can use the commands below:
- Certificate Authority secret
# kubectl create secret generic <resourcename>-custom-certs \
--from-file=ldap-ca.crt=<PATH/TO/YOUR/CA/PEM/FILE> \
--from-file=bundle-ca.crt=<PATH/TO/YOUR/CA/PEM/FILE>
- LDAP BIND DN Password secret
# kubectl create secret generic <resourcename>-ldap-password \
--from-literal=ldap-password=<your_ldap_dn_password>
A sample of extra settings can be found as below:
- setting: AUTH_LDAP_SERVER_URI
value: >-
"ldaps://ad01.abc.com:636 ldaps://ad02.abc.com:636"
- setting: AUTH_LDAP_BIND_DN
value: >-
"CN=LDAP User,OU=Service Accounts,DC=abc,DC=com"
- setting: AUTH_LDAP_USER_SEARCH
value: 'LDAPSearch("DC=abc,DC=com",ldap.SCOPE_SUBTREE,"(sAMAccountName=%(user)s)",)'
- setting: AUTH_LDAP_GROUP_SEARCH

value: >-
"CN=operators,OU=Groups,DC=abc,DC=com"
- setting: AUTH_LDAP_USER_FLAGS_BY_GROUP
value: {
"is_superuser": [
"CN=admin,OU=Groups,DC=abc,DC=com"
]
}
- setting: AUTH_LDAP_ORGANIZATION_MAP
value: {
"abc": {
"admins": "CN=admin,OU=Groups,DC=abc,DC=com",
"remove_users": false,
"remove_admins": false,
"users": true
}
}
- setting: AUTH_LDAP_TEAM_MAP
value: {
"admin": {
"remove": true,
"users": "CN=admin,OU=Groups,DC=abc,DC=com",
"organization": "abc"
}
}
In cases which you want to persist the /var/lib/projects
directory, there are few variables that are customizable for the awx-operator
.
Name | Description | Default |
---|---|---|
projects_persistence | Whether or not the /var/lib/projects directory will be persistent | false |
projects_storage_class | Define the PersistentVolume storage class | '' |
projects_storage_size | Define the PersistentVolume size | 8Gi |
projects_storage_access_mode | Define the PersistentVolume access mode | ReadWriteMany |
projects_existing_claim | Define an existing PersistentVolumeClaim to use (cannot be combined with projects_storage_* ) |
'' |
Example of customization when the awx-operator
automatically handles the persistent volume could be:
---
spec:
...
projects_persistence: true
projects_storage_class: rook-ceph
projects_storage_size: 20Gi
In a scenario where custom volumes and volume mounts are required to either overwrite defaults or mount configuration files.
Name | Description | Default |
---|---|---|
extra_volumes | Specify extra volumes to add to the application pod | '' |
web_extra_volume_mounts | Specify volume mounts to be added to Web container | '' |
task_extra_volume_mounts | Specify volume mounts to be added to Task container | '' |
ee_extra_volume_mounts | Specify volume mounts to be added to Execution container | '' |
init_container_extra_volume_mounts | Specify volume mounts to be added to Init container | '' |
init_container_extra_commands | Specify additional commands for Init container | '' |
โ ๏ธ Theee_extra_volume_mounts
andextra_volumes
will only take effect to the globally available Execution Environments. For customee
, please customize the Pod spec.

In order to register default execution environments from private registries, the Custom Resource needs to know about the pull credentials. Those credentials should be stored as a secret and either specified as ee_pull_credentials_secret
at the CR spec level, or simply be present on the namespace under the name <resourcename>-ee-pull-credentials
. Instance initialization will register a Container registry
type credential on the deployed instance and assign it to the registered default execution environments.
The secret should be formated as follows:
---
apiVersion: v1
kind: Secret
metadata:

The images listed in "ee_images" will be added as globally available Execution Environments. The "control_plane_ee_image" will be used to run project updates. In order to use a private image for any of these you'll need to use image_pull_secrets
to provide a list of k8s pull secrets to access it. Currently the same secret is used for any of these images supplied at install time.
You can create image_pull_secret
kubectl create secret <resoucename>-cp-pull-credentials regcred --docker-server=<your-registry-server> --docker-username=<your-name> --docker-password=<your-pword> --docker-email=<your-email>
If you need more control (for example, to set a namespace or a label on the new secret) then you can customise the Secret before storing it
Example spec file extra-config
---
apiVersion: v1
kind: Secret
metadata:
name: <resoucename>-cp-pull-credentials
namespace: <target namespace>
data:
.dockerconfigjson: <base64 docker config>
type: kubernetes.io/dockerconfigjson

To uninstall an AWX deployment instance, you basically need to remove the AWX kind related to that instance. For example, to delete an AWX instance named awx-demo, you would do:
$ kubectl delete awx awx-demo
awx.awx.ansible.com "awx-demo" deleted
Deleting an AWX instance will remove all related deployments and statefulsets, however, persistent volumes and secrets will remain. To enforce secrets also getting removed, you can use garbage_collect_secrets: true
.
To upgrade AWX, it is recommended to upgrade the awx-operator to the version that maps to the desired version of AWX. To find the version of AWX that will be installed by the awx-operator by default, check the version specified in the image_version
variable in roles/installer/defaults/main.yml
for that particular release.
Apply the awx-operator.yml for that release to upgrade the operator, and in turn also upgrade your AWX deployment.
Starting with awx-operator 0.14.0, AWX can only be deployed in the namespace that the operator exists in. This is called a namespace-scoped operator. If you are upgrading from an earlier version, you will want to
delete your existing awx-operator
service account, role and role binding.
Starting with awx-operator 0.14.0, the project is now based on operator-sdk 1.x. You may need to manually delete your old operator Deployment to avoid issues.
Delete your old AWX Operator and existing awx-operator
service account, role and role binding in default
namespace first:
$ kubectl -n default delete deployment awx-operator
$ kubectl -n default delete serviceaccount awx-operator
$ kubectl -n default delete clusterrolebinding awx-operator
$ kubectl -n default delete clusterrole awx-operator
Then install the new AWX Operator by following the instructions in Basic Install. The NAMESPACE
environment variable have to be the name of the namespace in which your old AWX instance resides.
Once the new AWX Operator is up and running, your AWX deployment will also be upgraded.
Please visit our contributing guidelines.
The first step is to create a draft release. Typically this will happen in the Stage Release workflow for AWX and you dont need to do it as a separate step.
If you need to do an independent release of the operator, you can run the Stage Release in the awx-operator repo. Both of these workflows will run smoke tests, so there is no need to do this manually.
After the draft release is created, publish it and the Promote AWX Operator image will run, which will:
- Publish image to Quay
- Release Helm chart
This operator was originally built in 2019 by Jeff Geerling and is now maintained by the Ansible Team
